' Snoqualmie Falls, in the county of King and State of Washington, have invented new and useiul lmprovcments in Cultivators, of which the following is a specification.

The object of the invention is to provide a relativly simple and. efficient construction 01 cultivator for preparing the surface of soil for seeding' and adapted to operate under such condition-S as'to insure -a uniform action up0n all portions of the surface travrsed by the machine, to the end that soil of whioh the surface is uneven may be cultivated to a uniform depth; and further more to provide means whereby the cultivating or soil working elements may be separately or independently withdrawn from operative relation with the soil to provide spaces to correspond with rows of growing plants or crops between which it is desired 'to cultivate the soil without disturbance of or injury to the plants; and urthermore to provide a device Which Will combine the it Will cultivate and weed the ground at the same time and with these objects in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the drawing, WhGIB- in: Figure 1 is a plan view of the machine.

Figure 2 is a side view'of the same.

Figure 3 is a detail vieW of a portion of one of the hanger bars. 7

Figure 4 is a view in perspective of a portion of the frame showing the means for supporting the rear series of draw bars.

The trame of the machine preferably consists of the marginal beam 10 of angle bar form having the extremities of the axle 11 secured thereto as by means of clips 12, the ground wheels ,13 being mounted upon spindle portions 14 at the ends of said axle the portions of the side members 10 of said beam in front of the plane of the axle being inclined dowmvard to position the front transverse portion 10 thereof below the plane of the stub tongue 15 which is attached at its rear end to and extends forwardly from the axle, the forward depressed portion of said marginal trame being supported from the stub tongue by a .hanger 16 as shown clearly in Figure 2. The seat standard 17 may be attached as shown'tothe r'ear end of the stub torigue,which is secured to the central portion of the aide by a clip 18 and is strengthened bythe diagonally disposed forwardly extending bracs 195 Parallel withthe transverse frontmember ofthe depressed forwardly cxtending por-- heing designed for engagement by the bifurcated or yoke shaped porti0ns23 of;fiont and rear ser1es of draw bars 24-Whi0h carry the plow or shovel standards .25, to the end that while the-yokes at.the forward ends serve to properl v space thedraw bars trans= versely with reference to the path of the cultivator, fre vertical swinging movement of the draw bars independently of each other is permitted, to the end that the plows or shovels carried by the standards at' the free rear ends thereof may follow accurately the inequalities or irregularities of the soil traversed by the machine to insure a uniform depth of cultivation regardless of' such irregularities.

In the construction illustrated a pilot or coltcr wheel 26 is mounted in a depending colter frame 27 connected by a fifth wheel.

28 with thetorward end of the. stub tongue, said colter frame being provided with a forward extension 29 for attachment to the draft tongue 30.

The plow or shovel standards are preferably looped-at their upper ends as shown at 31 and the loops are attached at their front and rear sides of rivets 32 in the Split or divided reai ends of the draW bars, t0 af'ord a forward and rearward resilience or spring quality to the standards to cushion strains or jars due to the contact 01 the cultivator shovels 33 with obstacles in the paths of their movemcnt, said loops also forming convenient handles or grips b v which the rear ends of the draW bars with the attached standards may beh1anually raised for enr gagement with hangerhooke 34 supported by transverse hangerbars 35 and 36 ClS-' tien to another and the support of selected bars being desirabe when "sol is being cultivated bebWeen par aflel rows of growing p1ancs, t0 avod -the dsturbance or injury of. Tht'rear hanger bar 35 is ter the plants. minafly attached to and supported by the rearwardly extending portions of the side members of t-he marginal framebeamr whle the forward hangar bar is terminaHy attached to and supported by thedownwardly A and forwardly inclined front portions of na1 frame while th latter extend rm the- 1ear' hanger bar 130 the front hanger bar, the braces 27 being intermediaely attached to the aX1e. f

-Having dscribed the inventidn, what clamed as new and useful s:'

'A cultivator havng a marg1nal frame r nature. r

beam havingparallel side; members and a connectngfront member, a transverseaxle securdto the side members of the marginal frame.between the front and rear ends ther ofand having supPorting wheels mounted upon spindles at the extremies thereof, said marginal frame being downwardly and forwardly inclined in advance of the plane of the a-xle, a stub tongue secmed at its rear end 130 the axle and connected with the transVerse front member of said marginal fram by a hanger, and front and rear series of indep endent standard carrying draw bar-s fulcrumed upon said frame,the sad-seres ofdraw bars being connected wththe frame by transverse fu1crum r o ds th, front rod connectingthe side portions of the marginal -frafne and the rear rod b eingj -carned;by hangars dependmg fr0m sa 1d sde portions in the plane of the axle.
